Abstract: An antibacterial peptide P104 and a lysin LysP53 with broad-spectrum lytic activity and applications thereof are provided. The amino acid sequence of the antibacterial peptide P104 is shown as SEQ ID NO: 1, and the gene sequence of the antibacterial peptide P104 is shown as SEQ ID NO: 3. The amino acid sequence of the lysin LysP53 is shown as SEQ ID NO: 2, and the gene sequence of the lysin LysP53 is shown as SEQ ID NO: 4. The antibacterial peptide P104 and the lysin LysP53 have lytic activity against Gram-negative bacteria, such as Acinetobacter baumannii, Pseudomonas aeruginosa, Klebsiella pneumoniae and Escherichia coli The lysin LysP53 can be subjected to soluble expression by Escherichia coli, and the activity of the lysin is high. Therefore, they have good application prospects in the research and development of anti-infective drugs.

Abstract: The present disclosure discloses a method for automatically identifying south troughs by improved Laplace and relates to the technical field of meteorology. The method includes the following steps: acquiring grid data of a geopotential height field; calculating a gradient field of the geopotential height field in an x direction; searching for a turning point where a gradient value turned from being negative to being positive, and cleaning the gradient field; calculating a divergence of the x direction to obtain an improved Laplacian numerical value L?; performing 0,1 binarization processing on the L? to obtain a black-and-white image and a plurality of targets of potential troughs, merging the black-and-white image and the plurality of targets of the potential troughs by expansion, recovering original scale through erosion, and selecting an effective target through an angle of direction of a contour and an axial ratio.

Abstract: In accordance with embodiments of the present disclosure, a voltage rectifier may include: an AC/DC converter, a first DC/DC converter, and a second DC/DC converter. The AC/DC converter may be configured to convert an AC source voltage to a DC bus voltage. The first DC/DC converter may be configured to convert the bus voltage to a DC compensating voltage having an AC ripple to compensate for AC ripple of the bus voltage. The second DC/DC converter may be configured to convert a DC compensated bus voltage to a DC output voltage, wherein the DC compensated bus voltage is equal to a difference between the bus voltage and the compensating voltage.
